32 Claims.

The present invention relates to the treatment of yarns by the application thereto of a liquid treating material, for example, a sizing liquid, its principal object being the production of such yams in the form of hanks. It is a further object of the invention to carry out the twistingof yarns simultaneously with the liquid treatment and theformation of the yams into hanks.

, The invention is of particular advantage in the application of a sizing liquid to the yarn, but it will be understood that treating liquids other than sizes may be applied to the yarn during the hanking operation.

According to the invention yarn is led from a of heat. Thus the reel may be wholly or partially enclosed in a heated atmosphere, or sur roimded by heated pipes, air being directed on to the yarn on the reel either by the rotation of the reel itself or by the aid of a suitably disposed suction fan or blower.

The yarn 'may be drawn from any kind of packages, such as bobbins, cheeses, or hanks, and separate reels may be used for each yarn 'to be hanked' or the reels may be of such a'length as to accommodate several hanks.

In order to prevent kinks being formed in the hanks, particularly when the yarns have been treated with size, it is preferred to use a reel having a cylindrical periphery. For example, a cylindrical-shell of perforated metal may be removabiy mounted on the arms of the reel, or each arm may have connected thereto a curved perforated plate extending to and resting on the next arm.

The operation may be accompanied by"a twisting of the yarn as it is drawn from the package, the twisting taking place at a rate governed by the degree of twist and the speed of hanking.

The invention which-is applicable to the treat ment of all sorts of textile yarns, but is particularly useful for the treatment of cellulose acetate or other forms of artificial silk, whether in the form of continuous filaments or spun yarn, enables the production of hanks of treated yarn to becarried out at a high rate, and allows of Great Britain May 24, 1930 large amounts of yarn being treated without frequent stoppage of the operation.

The invention will now be described in greater detail with reference to the accompanying drawing and in its particular application to the treatment of yarns with a sizing liquid, but it is to be understood that the following description is given by way of example only, and is in no respect limitative. Fig. 1 is a side elevation, partly in section, of 10 the sizing machine according to the invention. Fig. 2 is a front elevation of the machine shown in Fig. 1.

Referring to the figures, a bobbin 5 is mounted on a spindle 6, driven from a wharl I. The yarn 15 8 is led from the bobbin 5 to a balloon guide 9 and thence to a tensioning guide It, consisting of two staggered bars II and I2. The tension guide l0 provides the required tension in the yarn as it passes over the sizing device. The sizing device consists of a bath or trough it containing the .sizing material, into which dips a furnishing roller l4, size being transferred from the furnishing roller to a sizing roller ll over which the yarn passes. The yarn is held in contact with 25 the roller I5 bya guide bar it. A coating of size is imparted to the yarn as it passes over the roller I 5, the yarn being then led to the first guide ll of the reeling mechanism. From the stationary guide II the yarn passes to the traversing guide l8, carried upon the traversing rod i9 which is oscillated by means of a'crank I Q'to lay the yam in diamond pattern as a hank 20 "upon the reel II.

In order to avoid kinking of the sized thread in the hank 20, the reel 2| is constructed of a perforated metal sheet 22, bent into the form of a cylinder and sprung outwards by the arms 23 of the reel, which are mounted on a shaft 24. The edges 22' of the sheet 22 abut against one another over one of the arms 23. The whole reel is contained in a casing 25, with end plates 28 cut away to a suitable shape at 21, to allow the shaft 24 to pass through. The shaft 24 is mounted on bearings 28, 29 outside the casing 25, one of which bearings, as at 28, may conveniently. be a U-bearing. In the modification shown, a large reel is used, driven by a. pulley 28', capable of receiving a number of hanks 204 The winding operation is started onall the hanks simultaneously, and when winding is completely the entire reel 2| is removed from'the casing by lifting one end of the shaft 24 out of the U-bearing 28, and sliding the whole reel 2| out of the casing 2|. .Thesizedyarnonthereelisdricdwhiieitis being wound by means of heating pipes 3| partly surrounding the reel, and supplied with steam from a header 32, the steam being withdrawn from an exhaust header 33. Air is drawn through the casing 25 during the rotation of the reel by means of a suction fan 34 and air trunks .35. The air impinges upon the sized yam to dry the size, circulation through the inside 01. the reel 24 being permitted 'by the perforations 36 in the metal sheet 22. Fig. 1 a portion 26 of a similar machine is shown through which air is drawn by the same Ian 34. It will be clearthat the remainder of this machine is precisely similar to that already described, the two being disposed symmetrically.

As shown in Fig. 1, and on the left-hand side of Fig. 2, the yarn may be twisted as it leaves the supply packages 5, which are rotated by means of the wharl I, at a rate higher than the winding-off rate of the yarn. Alternatively, .as shown on the right-hand side of Fig. 2, the yarn may be 'taken from cones 31 or other suitable packages without twisting, and passed through the balloon guide 9 to the sizing device. In this case the cone will simply be mounted upon a peg 38.

On removal of the reel 2| from the jacket 25, the support .01 the arms 23 is withdrawn, so that the cylindrical sheet 22 collapses, permitting the removal of the hanks. The hanks may then be placed on cores or formers or otherwise packed for transport or they may be rewound into any desired form 01' package.

It will be seen that in.

The size which is applied to the yarn may be of any kind suitable or appropriate to the yarn under treatment to provide a coating of dressing having any desired characteristics. For example, in the case of cellulose acetate yarn starch size, gelatine size, with or without softening agents such as castor oil or glycerin, or the sizes described in U. S. applications S. Nos.

bothof 10th February 1931 and U. S. application 10 S. No. 535,287 filed March 5, 1931 may be used.

What we claim and desire to secure by Letters Patent is:-

1. Apparatus for the treatment of yarns, comprising in combination a twisting device adapted .to support a yarn package, means for applying a. liquid to twisted yarn drawn from said package, a winding device for forming the treated yarn into a. bank, a casing surrounding said winding device, and means for supplying a drymg, medium to the interior of said casing.

2. Process for the treatment of yarns and the like comprising, as a continuous operation, drawing yarn from a package, twisting the yarn as it leaves the package, applying a liquid to the yarn, winding the yarn in the form of a hank, supplying a drying medium to the hank during winding and maintaining the hank substantial- 1y enclosed during the operation so as to concentrate thereon the action of the drying medium.
